Summary
This study tests whether frozen capsules containing processed stool from healthy donors can help people with mild-to-moderate active ulcerative colitis. Participants will take either the real capsules or a placebo for 12 weeks. The goal is to see if the treatment can bring the disease into remission without the need for ongoing strong medications.
